Description

Technical Field

[0001] This utility model relates to the field of crystallization apparatus technology, and more specifically, to a cooling crystallization apparatus for phenol preparation. Background Technology

[0002] In existing technologies, existing cooling crystallization devices fail to provide an efficient and convenient material stirring system during use. In the process of phenol crystallization, uniform stirring of materials is crucial to ensuring the quality and speed of crystallization. However, the stirring mechanism in existing devices often suffers from problems such as inflexible operation and uneven stirring effect. This can lead to local overcooling or insufficient crystallization of materials during the crystallization process, which in turn affects the purity and yield of the product.

[0003] Under current technological conditions, the cooling crystallization device used for phenol preparation still has significant technical shortcomings in the material discharge stage. In particular, blockages are prone to occur during material discharge, and these blockages cannot be easily and quickly resolved, which seriously affects the overall operating efficiency and stability of the device.

[0004] The phenol crystallization process has strict temperature requirements and requires a precise and efficient cooling system to ensure that phenol crystallizes rapidly and uniformly at the optimal crystallization temperature. However, the cooling function design of existing devices has problems. During the use of traditional cooling systems, some materials may overheat or be not cooled completely. This not only makes the crystallization process unstable, but may also lead to a decrease in the quality of phenol crystals and even produce some undesirable byproducts. Utility Model Content

[0010] The present invention is further provided that the bottom of the stirring cylinder is provided with a support seat, and the support seat is used to facilitate the completion of the support process for the stirring cylinder.

[0011] The present invention is further configured such that a movable plate is threadedly connected to the threaded rod, and the movable plate is slidably connected to the guide rod, thereby facilitating the completion of the drainage process of the discharge pipe by using the movable plate.

[0012] The present invention is further configured such that a stop bar is installed on the movable plate, and the stop bar is used to facilitate the completion of the material handling process.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cooling crystallization apparatus for phenol preparation, which has the following beneficial effects:

[0018] 1. The mixing assembly, through its reasonable structural design, effectively improves the mixing effect of materials. First, the rotation of the stirring rod drives the rotating rod, rotating blades and connecting blades to carry out all-round mixing, which can ensure that the materials are evenly distributed in the mixing drum and avoid unevenness during the crystallization process. In particular, the spiral blade design on the connecting blades can increase the mixing intensity of materials, ensure that the materials form an ideal crystal structure during the crystallization process, and optimize the crystallization effect of phenol.

[0019] 2. The sealing assembly plays a crucial role in material discharge. The second motor drives the threaded rod, which allows the moving plate to slide smoothly under the guidance of the guide rod. This adjusts the movement of the abutment rod, and the tight contact between the sealing gasket on the abutment rod and the top of the discharge pipe effectively seals the mixing drum, preventing material leakage or evaporation.

[0020] 3. The cooling component introduces cooling water into the outside of the mixing drum through the outer shell, thereby achieving effective cooling of the material. The circulating flow of cooling water can quickly remove heat from the material, control the material temperature, and avoid overheating or temperature fluctuations during the crystallization process, thus ensuring the quality and stability of phenol crystals. In addition, the design of the inlet and outlet pipes of the cooling component allows for precise control of the cooling water flow, making the cooling effect more stable and uniform, and avoiding crystallization failure or low crystallization efficiency due to uneven cooling.

[0030] Please see Figures 1-5 A cooling crystallization apparatus for phenol preparation includes a stirring drum 1. A stirring assembly is mounted on the stirring drum 1, comprising a first motor 2, a stirring rod 3, a rotating rod 4, a rotating blade 5, and a connecting blade 6. The first motor 2 is fixedly mounted on the stirring drum 1. The stirring rod 3 is connected to the output end of the first motor 2. The rotating rod 4 is evenly distributed on the stirring rod 3. The rotating blade 5 is disposed on the rotating rod 4. The connecting blade 6 is disposed on the stirring rod 3. A sealing assembly is mounted on the stirring drum 1, comprising a second motor 7, a threaded rod 8, and a guide rod 9. The second motor 7 is located at the top of the stirring drum 1. The threaded rod 8 is connected to the output end of the second motor 7. The guide rod 9 is disposed inside the stirring drum 1.

[0031] A spiral blade 10 is connected to the connecting blade 6.

[0032] The bottom of the mixing drum 1 is provided with a support base 11.

[0033] The threaded rod 8 is threadedly connected to a movable plate 12, which is slidably connected to the guide rod 9.

[0034] A stop bar 13 is installed on the movable plate 12.

[0035] A sealing gasket 14 is installed on the abutment rod 13, and the sealing gasket 14 is in close contact with the top of the discharge pipe 17.

[0036] In this embodiment, during use, the material is injected into the mixing drum 1 along the feed pipe 18. The first motor 2 is started, which drives the stirring rod 3 at the output end to rotate. During the rotation, the rotating rod 4 on the stirring rod 3 rotates, and the rotating blade 5 on the rotating rod 4 promotes the mixing of the material. During the rotation of the stirring rod 3, the connecting blade 6 on the stirring rod 3 rotates, which in turn drives the spiral blade 10 connected to it to complete the mixing of the material. After the mixing process is completed, when it is necessary to discharge the material, the second motor 7 is started, which drives the threaded rod 8 at the output end to rotate. During the rotation, the moving plate 8 on the threaded rod 8 moves along the guide rod 9, which moves the abutting rod 13 from the discharge pipe 17. During the movement, the sealing gasket 14 on the threaded rod 8 moves out, which releases the seal on the mixing drum 1, allowing the material to be discharged from the discharge pipe 17. The movement of the abutting rod 13 also clears any blockages in the discharge pipe 17.

[0037] Please see Figure 1-3 As an embodiment of a cooling crystallization device for phenol preparation, the cooling component is provided on the outside of the stirring drum 1. The cooling component includes a shell 15, a water inlet pipe 16 and a discharge pipe 17. The shell 15 is sleeved on the outside of the stirring drum 1, and the water inlet pipe 16 and the discharge pipe 17 are respectively installed at the upper and lower ends of the shell.

[0038] A feed pipe 18 is installed on the mixing drum 1, and valves 19 are installed on the water inlet pipe 16 and the discharge pipe 17. A support plate 20 is installed at the bottom of the support base 11.

[0039] More specifically, during use, the two external water pipes are connected to the inlet pipe 16 and the drain pipe respectively, and the valve 19 installed on them is used to control the flow rate of the water. This allows the cooling water to be introduced into the outer shell 15 along the inlet pipe 16 during use, thereby cooling the material inside the mixing drum 1. After use, the valve 19 on the drain pipe is used to control the discharge of the cooling water.

[0040] In summary, during the use or operation of the overall equipment: Material is injected into the mixing drum 1 along the feed pipe 18. The first motor 2 is started, causing the stirring rod 3 at the output end to rotate. During this rotation, the rotating rod 4 on the stirring rod 3 rotates, and the rotating blades 5 on the rotating rod 4 further promote the mixing of the material. Furthermore, the rotation of the stirring rod 3 causes the connecting blades 6 on the stirring rod 3 to rotate, thereby driving the spiral blades 10 connected to it to further promote the mixing of the material. During the mixing process, and after the mixing process is completed, when it is necessary to discharge the material, the second motor 7 is started, which drives the threaded rod 8 at the output end to rotate. During the rotation, the moving plate 12 on it slides along the guide rod 9, thereby causing the abutment rod 13 on it to move out of the discharge pipe 17. During the movement, the sealing gasket 14 on it is moved out, thereby releasing the seal on the mixing drum 1, so that the material can be discharged from the discharge pipe 17. In addition, the movement of the abutment rod 13 can clear the blockage in the discharge pipe 17.

[0041] During use, the two external water pipes are connected to the inlet pipe 16 and the drain pipe respectively, and the valve 19 on them is used to control the flow rate of the water. This allows the cooling water to be introduced into the outer shell 15 along the inlet pipe 16 during use, thereby cooling the material inside the mixing drum 1. After use, the valve 19 on the drain pipe is used to control the discharge of the cooling water.
